Under updates to the FISA law enacted in 2008, the government has the ability to compel US phone companies and internet providers to provide access to communications across the backbone of the internet.

The trove of data, including a large portion of US internet traffic, is meant to provide US intelligence agencies with quick access to data regarding foreigners in other countries.
According to the National Security Agency, 60% of what appears in the Presidential Daily Brief has some data that comes from the 702 program. The Oversight Board report says searches of the data are critical to informing the US understanding of Russias aggression against Ukraine, foreign actors plotting cyberattacks in the US and Chinas targeting of dissidents.
